Start with the vet, almost every time
Behaviour and health are tangled together in cats. A cat who suddenly bites when stroked may have a sore spine or arthritic hips; a cat who stops using the litter tray may have a painful urinary problem; an older cat who yowls at night and seems restless may have a medical cause a vet can test for. So the first appointment for any new, sudden, or worsening behaviour is with your veterinarian, not a behaviourist. If the medical side comes back clear, or once treatment is under way, that is when behaviour help earns its place — and your vet's referral usually leads to a properly qualified practitioner.
The clearest reasons to book behaviour help
Danger tops the list: bites that break skin, attacks on people that come without warning, or fights between household cats that leave wounds. Persistence is the second: spraying, toileting outside the tray, or night-time vocalising that continues for weeks after you have fixed the obvious triggers like tray number, placement, and cleanliness. Welfare is the third: a cat who hides almost all day, stops playing and grooming, or cannot relax even in quiet rooms is living with more stress than home tweaks usually shift. Sudden personality change in a senior cat also belongs here once medical causes are checked.
What a good behaviourist actually does
Expect questions, not instant answers. A qualified feline behaviourist will take a detailed history — your cat's early life if known, the layout of trays, food, and resting spots, who else lives in the home, and a precise account of when the problem happens. Many will want video of the behaviour, taken safely when it occurs naturally, never staged. The output is a written plan that changes the environment and your routines in small steps, with follow-up to adjust it. Be wary of anyone who guarantees a cure, wants to punish the cat, or diagnoses a medical cause themselves.
What to gather before the appointment
Write down the pattern while it is fresh: dates and times of episodes, what happened in the ten minutes before, where in the home, and who was present. Note appetite, water intake, tray habits, and sleep changes alongside, because behaviourists and vets both read those clues. A week of honest notes beats a month of general impressions. Photograph the home setup too — tray locations, feeding stations, and high perches — since resource placement is often part of both the problem and the fix.
Making the plan stick at home
Behaviour plans fail less from bad advice than from patchy follow-through: one person follows the new feeding routine while another keeps free-feeding, or the plan's steps get skipped during a busy week. Share the plan with everyone who handles the cat, put its daily steps somewhere visible, and review progress at the follow-up rather than quietly abandoning it. If the behaviour worsens at any point, or new signs like appetite loss or straining in the tray appear, go back to your vet promptly rather than waiting for the next behaviour session. In KinsLe, Kimmy is there to ask in the moment while you collect those episode notes, helping you organise what you have seen alongside your cat's profile before the professionals weigh in.
